What is congenital heart disease? Congenital heart disease is a congenital malformation of heart development, the incidence is 6-8 per 1,000, there is a common saying that many congenital heart disease “can be cured at the age of a few years, a few dozen years old become difficult to cure, to dozens of years old becomes incurable “The most important thing is to make sure that the patient’s heart is in good condition. How is the danger of congenital heart disease Congenital heart disease is caused by abnormal development of the heart and blood vessels during the fetal period, and children with severe malformations die weeks or months after birth. With the rapid development of medical technology, most children can grow up healthier with medical and surgical treatment, but if left untreated, they often develop disabilities or die in the middle of their lives. What can cause congenital heart disease? There are three main factors affecting fetal heart development: (1) external environmental factors: the more important ones are intrauterine infections, such as rubella, influenza, mumps and so on. Large amounts of exposure to radiation, advanced maternal age and smoking and drinking can cause congenital heart disease. (2) Genetic factors. (3) Nutritional factors. Although the cause of congenital heart disease is still unclear, it is of positive significance to prevent congenital heart disease by strengthening health care during pregnancy, especially by actively preventing rubella, influenza and other viral diseases in early pregnancy and avoiding all factors related to its development. How is the treatment of precocious heart disease? There are two types of treatment for precardiac disease, interventional and surgical. Interventional treatment is non-invasive, less invasive and quicker to recover. However, complex and severe precardiac diseases still rely on surgical treatment. Many treatable precardiac diseases may be delayed by the patient’s parents, resulting in the child losing the opportunity for surgery and often regretting it too late. Therefore, the discovery of abnormalities in the child’s heart requires a formal diagnosis and treatment at an experienced hospital. What are the diagnostic bases of precardiac disease? Clinical manifestations: cyanosis or heart failure should be noticed in newborns and infants, while in young children and older children it can be detected during physical examination due to growth retardation and easy fatigue. Pallor, cold extremities, shortness of breath after activity, irritability, hoarseness, cyanosis or fainting may occur. Physical examination: lighter children generally have a normal appearance; more severe cases may affect intelligence and physical growth and development, and the liver and spleen may be enlarged. Special examination: echocardiography, cardiovascular angiography, etc. What is the best time to get help for precocious heart disease? Most of the patients with precocious heart disease can be cured radically and there will be no sequelae. However, the prerequisite for cure is timely detection and early treatment, and the earlier the treatment, the better the results. It can be cured at the age of a few years, difficult to cure at the age of a few dozen years, and not at the age of a few dozen years. For simple precocious heart disease, the age of treatment is usually around 3 years old and between 5 and 8 kg. However, severe and complex precordial diseases are treated in infants and children even at birth.
